borne but one good crop in
about 35 years. Mr. F. A. Bartlett, of Stamford, Conn., who knows
intimately many dozen trees of this species within a radius of 50 miles
of New York City, finds that few bear significant crops except at long
intervals. From Stamford, Conn., near the Atlantic Seaboard, south to
Norfolk, Va., Persian walnut trees are not uncommon in door-yards. They
are fairly frequent in southern Pennsylvania west over practically half
the length of the State and through Maryland west to Hagerstown. There
are perhaps more productive trees in Lancaster County, than in any other
county in either Pennsylvania or Maryland, with the possible exception
of some county of the Eastern Shore of the latter state, which section
already has been referred to. In Lancaster county yields are sufficient
to give considerable profit from trees not occupying expensive land.

The Japanese walnut affords a curious analogy in regard to hardiness.
During normal years, it succeeds over practically the same range as that
of the black walnut, yet it freezes in early fall, mild winter or late
spring when conditions are adverse, even when black walnut and pecan
nearby are not visibly affected. Mr. Jones finds the Lancaster heartnut,
a variety originating in his county, to be subject to injury by spring
freezing to such an extent that he has largely discontinued its
propagation. Mr. Edwin A. Surprise, of Boston, reports that this variety
grows well in summer but freezes back in winter about as much as it
grows in summer. Mr. Bartlett regards it as one of the most valuable
acquisitions in his nut planting at Stamford, Conn., as it is a
handsome, vigorous grower, and promises to bear well. As a safer variety
in the Lancaster district Mr. Jones has substituted the Faust from
Bamberg, S. C., which vegetates later in spring and thus far has proved
less subject to injury.

The twigs of young black walnut trees are occasionally injured by
freezing in winter, but recorded instances of such damage are rare. This
is a field which should be investigated, as there is evidently no data
showing even the regularity with which the black walnut bears in any
section, much less the extent to which fruiting is restricted by
destruction of the buds or spurs as a result of severe temperatures in
winter or spring. This also applies to hardiness of the butternut, the
hickories and of introduced species of chestnut.

In conclusion, it is pointed out that plante
